Bind-in insert

Abstract

A bind-in insert of lightweight paper stock for use in magazines, catalogs and booklets, has a paper envelope and a narrow, elongated, and impermeable thickened binding strip section disposed along the edge to be bound, the binding strip being formed by folding over and gluing the edge portion of the insert.

       2. The bind-in magazine assembly as set forth in claim 1, wherein: a. the line of separation includes opposed perforate lines on each panel of the envelope extending parallel to the length of the bind-in strip.
